本発明は、加工性、剛性、耐食性にすぐれた雨樋に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rain gutter with excellent workability, rigidity, and corrosion resistance.
ビルなど大型建造物に使用される雨樋は、腐食などによ

要となる。従って、長時間の耐久性が重要である。また
、美観の面では、第２図のような受は金具および雨樋形

方が、外観がすっきすしていてすぐれている。従って、
材料の剛性が重要になる。特に豪雪地帯では、雨樋の上
に積雪するため、剛性はより重要である。If the rain gutters used on large structures such as buildings become damaged due to corrosion, large-scale construction work such as setting up scaffolding will be required. Therefore, long-term durability is important. In addition, in terms of aesthetics, the metal fittings and U-shaped rain gutter shape shown in Figure 3 is better than the metal fittings and U-shaped rain gutter shape shown in Figure 2. . Therefore,
The stiffness of the material is important. Rigidity is especially important in areas with heavy snowfall, where snow accumulates on rain gutters.
従来の雨樋としては、塩化ビニル製、カラートタン類、
ステンレス製、銅製のものが知られている。Conventional rain gutters are made of vinyl chloride, colored galvanized iron,
Stainless steel and copper ones are known.
しかし従来のものには、それぞれ次のような問題点があ
る。However, each of the conventional methods has the following problems.
（ａｌ 塩化ビニル製
ビルなどに使用される大雨樋において、現在最も広く使
用されている材料は塩化ビニル製である。(al) Vinyl chloride The material currently most widely used in large rain gutters used for buildings and the like is vinyl chloride.
積雪地帯用として０．２龍厚の冷延鋼板を埋め込んだも
のもある。塩化ビニル製の欠点は耐久性が劣る点である

℃に加熱される。）冬の寒さを受けると、塩化ビニルと
冷延鋼板の間が剥訛し、塩化ビニル自体が破損する。そ
れに伴い、冷延鋼板が腐食する。また、塩化ビニルは強
度の面でも他の材料より低いため、剛性が小さい。そし
＋第１表に示すように引張強さが５ ｋｇ ／ 龍２程
度なので、ビルなどの大雨樋のよいに多量の雨水を処理
する場合は適さない。そして、雨樋を支える受は金具も
、単位長さ当りの個数が多くなり、トータルとしての製
造コストも高い。また、積雪地帯では、雪の重みに耐え
かね問題となっている。For use in snowy areas, there is also a type with 0.2mm thick cold-rolled steel plate embedded in it. The disadvantage of vinyl chloride is that it is less durable. In other words, outdoors, on a building wall in the heat of summer, approximately 130
heated to ℃. ) When exposed to the cold winter weather, the space between the vinyl chloride and the cold-rolled steel plate will peel, and the vinyl chloride itself will be damaged. As a result, the cold-rolled steel sheet corrodes. Furthermore, vinyl chloride has lower strength than other materials, so it has low rigidity. As shown in Table 1, the tensile strength is about 5 kg/2 kg, so it is not suitable for treating large amounts of rainwater from large rain gutters such as buildings. Furthermore, the number of supports and metal fittings that support the rain gutter increases per unit length, and the total manufacturing cost is also high. Additionally, in areas with heavy snowfall, there is a problem of not being able to withstand the weight of the snow.
さらに、塩化ビニル製雨樋は、ねずみ色をしており、建
築物の美観の点でも、ステンレス装の光沢、カラー鋼板
の色彩窓に比べ劣る。Furthermore, rain gutters made of vinyl chloride have a grayish color, and in terms of aesthetics, they are inferior to the luster of stainless steel cladding or colored windows made of colored steel sheets.
第 １ 表
（ｂ） カラー鋼板
カラー銅板は、ビル用の大雨樋にはほとんど使用されて

わち、曲げ加工部において、塗膜および下地処理として
の亜鉛メツキ被膜に剥雛が生じ、腐食が進行する。また
、亜鉛メツキの密着性の面から低強度の冷延鋸板が使用
されているので、引張強さは３５ｋｇ／ｍｍ”程度であ
り、しかも塗膜密着性の面から板厚も薄く規制されてい
る。Table 1 (b) Colored steel plates Colored copper plates are rarely used in large rain gutters for buildings. This is because there is a problem with corrosion resistance. That is, in the bent portion, peeling occurs in the paint film and the galvanized film as a base treatment, and corrosion progresses. In addition, low-strength cold-rolled sawn boards are used in order to ensure adhesion of the galvanized plating, so the tensile strength is approximately 35 kg/mm, and the board thickness is also regulated to be thin in order to ensure the adhesion of the coating. ing.
板厚は、それ以外に、高所での工事を行うため、厚いも
のは使いにくいという事からも薄物に限られている。こ
のため、剛性が小さくなり、大雨樋などへの適用は困難
である。In addition, the thickness of the boards is limited to thin ones, as thicker ones are difficult to use since construction is carried out at high places. For this reason, the rigidity is reduced, making it difficult to apply to large rain gutters and the like.
（Ｃ） ステンレス鋼板
ステンレス鋼板は、美観、耐食性、則性の面など、他の
材料よりすぐれているが、次の２点において問題がある
。(C) Stainless steel plate Stainless steel plate is superior to other materials in terms of aesthetics, corrosion resistance, and regularity, but it has the following two problems.
１つはステンレス鋼は加工硬度が大きく、加工しにくい
。すなわち第２表に示すように、焼鈍ままの状態では、
ステンレス畑も、ステンレスクラツド鋼も降伏点は約２
０ｋｇ１賞ｍ２と差が少ないが、５％の冷間歪を加える
と、ステンレス鋼は降伏点が１５ｋｇ／龍２上昇し、３
６ｋｇ／、、ｚとなり、ステンレスクラツド鋼の２７．
１ｋｇ／＊重２より硬くなる。これは、ステンレス鋼は
冷間加工により、オーステナイトが一部マルチンサイト
変態するためである。オーステナイトステンレス鋼特有
の性質である。One is that stainless steel has a high processing hardness and is difficult to process. That is, as shown in Table 2, in the as-annealed state,
The yield point of both stainless steel fields and stainless clad steel is approximately 2.
Although the difference is small from 0kg/m2, when 5% cold strain is applied, the yield point of stainless steel increases by 15kg/m2, and
6kg/,,z, 27. of stainless clad steel.
1kg/*harder than weight 2. This is because stainless steel undergoes a partial martinsite transformation of austenite during cold working. This is a characteristic unique to austenitic stainless steel.
もう１つの欠点は、熱膨張率が第３表のように大きい点
である。すなわち夏季には、モルタル建物の表面温度は
、１００℃程度に上昇するため１０ｍの長さの羊通は、
ステンレスクラ・ンド鋼、カラー鋼板ならば１２龍程度
、オーステナイト系ステンレス鋼では１７ｕ＋も膨張す
る。この膨張、収縮によって砧の結ぎ目がゆるみ、雨も
すなどの原因となる。Another drawback is that the coefficient of thermal expansion is large as shown in Table 3. In other words, in the summer, the surface temperature of a mortar building rises to about 100℃, so a 10m long Yotsutsu,
Stainless steel and colored steel plates will expand by about 12U, and austenitic stainless steel will expand by 17U+. This expansion and contraction causes the knots of the Kinuta to loosen, causing rain and other problems.
第３表
＋ｄ） 銅製
銅製雨樋は、加工性、剛性、耐久性、耐食性、美観など
、すぐれた点が多いが、以下の２つの欠点がある。Table 3 + d) Copper rain gutters have many excellent features such as workability, rigidity, durability, corrosion resistance, and aesthetics, but they have the following two drawbacks.
そ９１つは、緑青が発生し、雨水に溶けて周辺を緑色に
染め、色が落ちないので困ることである。The 91st problem is that it develops a patina, dissolves in rainwater, dyes the surrounding area green, and the color does not fade, which is a problem.
また、第４表に示すように、価格が極めて高いという欠
点もある。Furthermore, as shown in Table 4, it also has the disadvantage of being extremely expensive.
そこで、本発明の目的は、板厚を厚くできる剛性が大き
い、加工性が良好、加工部での被膜の剥離がない、被膜
の耐久性が良好、耐食性にイ■れる、洋風建築に通ずる
、価格が安いなど綜合的な特性が優れる雨樋を提供する
ことにある。Therefore, the purpose of the present invention is to provide high rigidity that allows the board to be thick, good workability, no peeling of the coating at processed parts, good durability of the coating, good corrosion resistance, and common to Western-style architecture. Our objective is to provide rain gutters with excellent comprehensive characteristics such as low prices.
上記問題点を解決するための本発明は、加工性に優れた
冷延柵板の表、裏面に、オーステナイト系ステンレス鋼
を、全板厚に対してそれぞれ５〜２０％の厚みをもって
クラッドしたことを特徴とするものである。In order to solve the above problems, the present invention is to clad the front and back surfaces of a cold-rolled fence board with excellent workability with austenitic stainless steel at a thickness of 5 to 20% of the total board thickness. It is characterized by:
本発明の雨樋は、冷延針板の表、裏面に、オーステナイ
ト系ステンレスｔ＋を、全板厚に対してそれぞれ５〜２
０％の厚みをもってクラッドしてなるものである。In the rain gutter of the present invention, austenitic stainless steel T+ is applied to the front and back surfaces of the cold-rolled throat plate at a rate of 5 to 20% of the total plate thickness.
It is made of cladding with a thickness of 0%.

オーステナイト系ステンレス鋼は、芯の冷延鋼板と強固
な冶金的接合をするため、加工工程および気候の変化な
どにより剥離したり、材質劣化することなく耐久性に優
れる。Therefore, since the austenitic stainless steel that is cradled and joined to the front and back surfaces of cold-rolled steel sheets has a strong metallurgical bond with the core cold-rolled steel sheet, it may peel off or deteriorate due to changes in the processing process or climate. Excellent durability without any damage.
引張強さとしては、第１表に示すように、４０〜５０ｋ
ｇ／＊＊２となり、剛性および加工性が十分に高いもの
となり、ビルなどの大雨樋に好適に使用できる。The tensile strength is 40~50k as shown in Table 1.

鋼製雨樋と同等であり、カラー鋼板、亜鉛メブキ鋼板よ
り大幅に良好である。As for the corrosion resistance, since the front and back surfaces are covered with austenitic stainless steel, it is equivalent to an austenitic stainless steel rain gutter, and is significantly better than colored steel sheets and zinc coated steel sheets.
加工性は、カラー鋼板と同等に優れ、第２表のように、
オーステナイト系ステンレス鋼製特有の加工硬化は認め
られず、冷間での折り曲げ加工性に優れる。The workability is as good as that of colored steel sheets, and as shown in Table 2,
No work hardening peculiar to austenitic stainless steel is observed, and it has excellent cold bending workability.
気温の変化による膨張収縮は、ステンレス口に比べて小
さく、第３表のように、カラー鋼板とほぼ同等である。Expansion and contraction due to changes in temperature are smaller than stainless steel plates, and as shown in Table 3, they are almost equivalent to colored steel plates.
外観はステンレス鋼と同等であり、ビルなどの洋風建築

優れた材料に比べて安価である。In terms of economy, as shown in Table 4, it is more expensive than materials with fatally inferior corrosion resistance and durability, such as colored steel plates and vinyl chloride, but it is more expensive than materials with excellent corrosion resistance such as copper and stainless steel. It is cheaper compared to
これらについて、本発明の雨樋と従来の雨樋との比較を
行うと、第５表のようになる。同表では、擾から劣につ
いて、順に◎、０１△、×で示しである。Table 5 shows a comparison between the rain gutter of the present invention and the conventional rain gutter. In the same table, grades from good to poor are indicated by ◎, 01△, and × in order.
以下本発明をさらに詳説する。 The present invention will be explained in more detail below.
本発明の雨樋は、第１図に示すクラッド被膜を素材とす

４を材質とする表裏面板２．３を、全板厚に対してそれ
ぞれ５〜２０％の厚みをもってクラフト接合してなるも
のである。The rain gutter of the present invention is made of a cladding film shown in FIG. In other words, 5pcc, which has excellent workability, is used as the core material.
Or use a cold-rolled steel plate 1 of 5PCD class, and use austenitic stainless steel on the front and back surfaces, such as 5US30.
It is made by craft-bonding front and back plates 2.3 made of material No. 4 to a thickness of 5 to 20% of the total plate thickness.
この素材を、第３図に示すようにＵ字状（コ字状）に折
曲加工し、所要位置に受は金具を取付けて雨樋とする。This material is bent into a U-shape as shown in Fig. 3, and metal fittings are attached to the required positions to form a rain gutter.
本発明は、主にＷ≧１００ｍｍ、ｈ≧５０關以上の大雨
樋を対象とする。The present invention is mainly directed to heavy rain gutters where W≧100 mm and h≧50 mm or more.
ところで、素材の金板ｑ−ｔは、０．４〜ｌ、 ５ ｘ

た、表裏面板の板厚ｊｌ＋ ｔ２は、それぞれ全板厚
ｔの５〜２０％、特に１０〜１５％が好ましい。By the way, the material gold plate q-t is 0.4~l, 5 x
The thickness jl+t2 of the front and back plates is preferably 5 to 20%, particularly preferably 10 to 15%, of the total thickness t.
表裏面板の板厚が上記値未満だと、クラッド被膜の厚さ

する比率が高まり、加工硬化し易くなり、加工性が悪く
なる。If the thickness of the front and back plates is less than the above value, the thickness of the cladding film will be thin, which will cause the coating to break during bending, especially when bent at 90 degrees in a U-shape. Moreover, when the above value is exceeded, the ratio of austenitic stainless steel to the whole increases, making it easier to work harden and worsening workability.
